Landing pages are for marketing and they tend to be focused on a specific product, have calls to action, sales copy, etc. They often have a clear goal, such as getting visitors to sign-up or leave contact information. They're the page that adverts, marketing emails, and social media promotions link to.

Home pages are more diffuse and serve a different purpose—linking to multiple products, blogs, about us pages, customer support, and so on. If you only have one product, like an app, or it's a microsite dedicated to a single product, your home page might be a landing page, but it doesn't have to be and usually isn't for bigger companies.
